“…Selama satu dekade terakhir, rata-rata produksi kakao tahunan Indonesia berada pada angka rata-rata sekitar 683 kiloton (Aini et al, 2023) (Mateus et al, 2023). Ekstrak dari kulit buah kakao kaya akan kandungan potasium, lignin, selulosa, hemiselulosa, pektin, dan antioksidan (Veloso et al, 2020).…”

The side of the production of the Gunung Kidul Cocoa Fermentation Center, DIY, in the form of cocoa pod husk, can cause a buildup of rubbish and become a nest for fungi that cause disease. Maximizing the use of cocoa shell waste is an effort so that people can increase the use value of waste into products that have higher economic value, one of which is extracting the cellulose. Cellulose fiber has several advantages such as good mechanical properties, low density, environmentally friendly, abundant, cheap, non-toxic, easily degraded, and included in renewable natural resources. Cellulose is obtained through an extraction process with two stages, namely alkaline delignification and bleaching. Therefore, this research aims to utilize the potential of cocoa pod husk in cellulose extraction for optimum conditions for the bleaching process with NaOCl 5%, 8%, 10% and 12% through analysis of yield, water content, ash content and FTIR characterization. Based on research that has been carried out, optimum results for cellulose are obtained through bleaching NaOCl 8% which has the best level of lightness and a yield of 52%. Chesson datta characterization also shows that cellulose NaOCl 8% NaOCl has the lowest water content and ash content, namely 1.4% and 0.8% respectively. FTIR analysis shows that the optimum results have the -OH stretching functional group as a representation of cellulose at wave numbers 3206 cm-1, 3442 cm-1 and 3600 cm-1. The presence of a peak in the wave number indicates that the bleaching process has succeeded in isolating the cellulose in the cocoa pod husk.

“…The increase in the thickness of the panels is a consequence of water absorption and refers to the dimensional stability of the panel (VELOSO et al, 2020b). According to Silva et al (2015), this result can be explained by the gradual increase in the compaction ratio, leading to a decrease in the amount of resin per unit area.…”

his study aimed to use the petiole residues of miriti to partially replace pine wood and evaluate the effects of this incorporation on the physical and mechanical properties of the particleboards. Panels were produced with 0, 25, 50, and 75% of miriti in partial replacement of wood and 12% of urea-formaldehyde adhesive. The chemical-physical properties of miriti residues showed potential particleboard production as they were similar to those of pinewood. For the physical properties, the panels were classified as low density.There was an increase in the compression ratio and, consequently, in the hygroscopicity . For the mechanical properties, it was observed that the modulus of elasticity (MOE) and modulus of rupture (MOR) did not show any statistical differences. For perpendicular traction (PT), there was a significant reduction in 50%. Considering a general analysis of the physical and mechanical properties, up to 40% of mirti can be substituted, as in this situation they meet the properties mentioned in CS-236-66, except for PT for commercialization of the panels.

“…Legume species contain large amounts of N deriving from the atmosphere, so when they are pruned this atmospheric N might eventually be available for cocoa trees. The waste left on top of the soil undergoes decomposition and represent a major source of organic matter and nutrients in the ecosystem (Triadiati et al, 2011;Vellend et al, 2011;Veloso et al, 2020). Therefore, sustainable management of mineral nutrition in tree plantations should aim at exploring the use of these internal sources of nutrients to reduce the need for inorganic chemical fertilizers (Isaac et al, 2007b;Brunetto et al, 2011;Tscharntke et al, 2011).…”

“…Undoubtedly, the cocoa industry is a source of livelihood for millions of farmers but waste accruing from its cultivation is a major concern (de Araújo Veloso et al, 2020) and the leading global producers (Cote d'Ivoire and Ghana) that accounts for 63% of the global cocoa beans production in 2016/17 (ICCO 2017) have a lot of cocoa waste to manage. It is important to recount that just ten percent (10%) of the total cocoa fruit weight is utilized for cocoa beans products (Rojo-Poveda, et al, 2020) as the remaining ninety percent (90%) is left on farmlands as waste.…”
